Hi Lyn,
I live in Gippsland and am also a decendant from Thomas East Fletcher. I don't know what information you have but his last born son Henry was my Great Grandfather and died age 30 of pneumonia and left a wife and young family. The children were all fostered and his wife Elizabeth Jane Stewart vanished from all records I have traced so far.
thomas's wife Sarah Elizabeth Wilder has no death certificate but died 1867 and I think is buried at Carngham Cemetery.
I have as the parents of Thomas East Fletcher, Charles Fletcher and Ann Taylor and their family in 1841 as:
Elizabeth b 1820
Thomas East b 1821
Valentine b 1823
Sarah b 1826
Hannah b 1833.
Do not have children information before or after this family.
They live at 60 Lane End Great Marlow which seems to be in High Wycombe. Google Earth gives a view of the house but too modern to be our families I think. Dont know where the East comes in but must be before this family.
Hope to hear from you soon.
Maurice
